The Unseen Side of Singapore’s Bus System | Singapore Hour

Every morning, before the city wakes, buses are already on the move.

They pass through neighbourhoods, heading into the city as the day begins.

Connecting people, places and daily routines.

One journey at a time.

Singapore’s bus system spans the city with over 360 routes and 5,000 stops.

It’s designed for reach, frequency and flow.

With most buses running on time, almost to the minute.

But it took years of change to build the system we see today.

Singapore’s first buses were privately run in the early 1900s.

Small, noisy and prone to breakdowns.

Nicknamed “mosquito buses”, they made up most of the bus services up till the 1960s.

Operators ran different routes.

Some in the city centre, others on the outskirts.

There were plenty of buses.

But no system to bring it all together.

Over the decades, the government restructured the system.

Consolidating operators, standardising routes, upgrading the fleet and introducing central planning.

What began as a patchwork of services became a coordinated network across the city.

The day begins in a quiet depot, at 4am.

So in the morning when I arrive, I’ll report for duty.

The dispatcher will deploy me to a route.

Peng Kian is a bus captain.

A title that reflects how the role has changed.

Normally, people think a bus captain is just a bus driver.

Someone who ferries passengers from point A to point B.

But in Singapore, we do more than that.

We have to take care of passenger safety and also situations on the road.

Safety doesn’t start on the road.

It begins with the first checks.

Peng Kian powers up the systems, checks the exterior, then walks the cabin for one final look.

Once he’s on the road, the focus only sharpens.

It's not just about driving.

A bus is big.

You've got a lot of blind spots.

So you constantly have to watch the blind spots and the system.

So, focusing is very important.

With so much to watch, it helps to have backup.

The Mobileye system monitors lanes, tracks nearby vehicles and pedestrians and flags speeding.

It’s designed to catch what the driver might miss, before it becomes a problem.

There's one thing I like about this job.

I get to see a lot of different groups of people: working adults, the elderly, helpers.

You interact with all of them in just one morning.

It's quite fun.

You're engaging with all kinds of different people, on different routes, in different places.

Not every day is easy but he keeps going.

For the familiar interactions and the people who remind him why he does this.

On the road, bus captains respond to what’s in front of them.

Traffic, timing and whatever the day brings.

But behind the scenes, another team is watching the bigger picture.

They track live data, adjust routes and keep the network in sync.

Hello BOCC, how can I help you?

When something goes wrong on the road, the call often comes here first.

At the bus operations control centre, controllers like Sam keep an eye on every bus route.

Tracking delays, road conditions and how crowded buses are.

From his screen, he sees how it all connects.

Every day, I need to ensure that bus operations run smoothly and all the buses travel on schedule.

We also track the bus location, passenger loads and road conditions.

If there’s any sign of delay, we take action immediately.

Spotting the issue is just the first step.

The challenge is reacting fast.

Rerouting services, alerting ground teams and keeping things on time.

Okay, where’s the location?

You mean the road isn’t passable?

A fallen tree blocks a turn.

One bus is stuck.

As the bus captain waits at the scene, Sam’s already working through options.

Checking nearby buses, finding a detour and assessing how this might affect other buses down the line.

Sam calling from SMRT.

I have a situation.

The road isn’t passable for Service 973, along Petir Road turning into Bukit Panjang Road.

So I have to plan a diversion route.

We’ll go through Jelebu Road and Lompang Road.

It sounds simple.

But these are split-second calls based on experience, road knowledge and the pressure to get it right.

The diversion route has been approved.

Now, we follow this road, just turn here and skip these two bus stops.

The most challenging thing for me is time.

Because with every second that passes, things could get worse.

We need to react quickly and make decisions fast.

The actions we take can affect commuters on the road.

They might not be able to travel on time.

Moving buses across a city is one challenge.

Changing what powers them is another.

Singapore is gradually replacing its fleet with electric and hybrid buses.

Over 130 are already on the road.

But switching to electric isn’t just about the vehicles.

It means new infrastructure, new workflows and new ways to keep things running.

At another depot across the island, technicians are already getting to work.

I will check the exterior for you.

Shahrul has been a bus technician for eight years.

In the last two, his focus has shifted to maintaining Singapore’s growing fleet of electric buses.

From braking systems to high-voltage wiring, everything needs checking.

And it all starts with the batteries.

Technically, what I'm looking out for are any abnormalities in the wire harness or any problems with the AC or DC motors.

Inside each electric bus are multiple battery packs that contain many battery cells.

Their temperature and charge are tracked constantly to ensure the bus runs reliably.

If anything looks unusual, it’s flagged early for maintenance.

That’s why early checks matter.

Once the bus is on the road, the checks don’t stop.

Built-in systems with remote diagnostics track performance in real time, even while passengers are onboard.

If the bus is on the road, we can detect signs of future abnormalities.

So, we can call the bus back and carry out maintenance accordingly.

Technology helps.

But some checks still need to be done on the ground.

Under the bus are some of its most important systems. Also, the most exposed.

Brake lines, suspension and high-voltage cables.

Shahrul looks for cracks, corrosion or signs of wear.

Things that could put the whole vehicle out of service if missed.

It’s detailed, demanding work.

But Shahrul knows why it matters.

Double check the sensor.

Open the door.

Of course, it’s a cleaner and greener future.

There’s no smoke, so passengers enjoy a smooth ride with less noise.

As a bus technician, I feel proud and happy to be part of the team maintaining electric buses.

Singapore’s bus system didn’t start out smooth.

But today, it runs because of many hands behind the scenes.

Captains starting before sunrise.

Controllers adjusting the network in real time.

Okay, I have planned a diversion route.

And technicians keeping the next bus ready to go.

As of now, from this graph, it’s good.

Most of it goes unseen.

But it’s what makes the system work.
